Bug: The lint.yml workflow was updated to use client-id, but the variable vars.SENTRY_INTERNAL_APP_ID likely still contains a numeric App ID, not the required string Client ID.
_{Severity: HIGH}

Suggested Fix

Verify that the repository variable SENTRY_INTERNAL_APP_ID contains the string-based Client ID (e.g., Iv...) and not the numeric App ID. For clarity, consider renaming the variable to SENTRY_INTERNAL_APP_CLIENT_ID to match its contents and the naming convention used in other workflows.

not valid.

Location: .github/workflows/lint.yml#L30

Potential issue: The `lint.yml` workflow was migrated to use the
`actions/create-github-app-token` action, which requires a `client-id` input. The
workflow now passes the `vars.SENTRY_INTERNAL_APP_ID` variable to this `client-id`
parameter. However, the variable name suggests it still holds a numeric App ID, not the
string-formatted Client ID that the action expects. App IDs and Client IDs are different
identifiers. If the variable contains the old numeric ID, the action will fail during
authentication, causing the lint workflow to fail on every run. This will block the
auto-commit step from executing.
